What is the number of electrons shared between the atoms in a molecule of nitrogen, N2
1 answer:
Answer:
3 electrons is contributed from each Nitrogen atom.
Total 6 electrons are shared in N₂.
Explanation:
- Nitrogen is belong to group VA
- it have 5 electron in its outer most Shell.
- it need 3 electrons complete its octet to become stable.
- Nitrogen have total 7 electrons.
- its atomic number is 7
The electronic configuration of Nitrogen is as:
1s², 2s², 2p³
it exist in diatomic form standard temperature and pressure.
Nitrogen form covalent bond and share 3 electron from each side.
total 6 electron are shared between 2 nitrogen atom.
For Covalent bonding it can share its 3 electrons.

The correct option is e.
Explanation:
p-value is the probability value for a given statistical model, the probability that, when the null hypothesis is true.
For two two samples the formula of test statistics is
where,
is sample mean
is population mean.
is standard deviation.
n is sample size.
Variance is the square of standard deviation.
It means variance, mean, numbers of samples is used in calculation of p-value.
Degree of freedom define the shape of the t-distribution that your t-test uses to calculate the p-value.
p-value of a statistical test depends on all of the following, except median.
Therefore the correct option is e.
